As it is already customary in Mexico, citizens of all states will have to adjust their clocks as soon as winter starts in the territory. The end of the season marks a series of changes to be taken into account by everyone in the country, especially due to the alteration of the time in most of the states of the Mexican Republic. When, why, and what to do with the time in the coming days? The answer to this and other questions is in the following paragraphs.

Without wanting to go over the subject of the time change in Mexico, we warn you that the wintertime starts no less than this October 31, date on which many citizens will have to reinvent their lifestyle. On Sunday morning, the Aztec people open the doors to Daylight Saving Times (DTS) for the next six months.

When does Daylight Saving Time begin in Mexico?

In most of the country, the time will change this Sunday, October 31, but the municipalities belonging to Mexico's border strip will have to wait one more week. The northern border, for example, will change its time on the first Sunday of November at 2:00 a.m., that is, on November 7. In this same line, it is worth mentioning that the change will last until April 2022, when daylight saving time begins.

Wintertime: will the clock go back or forward?

when Sunday, October 31 arrives worldwide, anyone living in the Mexican Republic will have to set their clocks back one hour to 3:00 a.m. What does this mean? Well, when it is 3:00 in the morning, it will be 2:00. Consequently, on that day, the Mexican people will sleep one hour longer.

Important! This time change does not affect all Mexican states. In Baja California, Chihuahua, Coahuila, and Nuevo León, the time will remain the same, so if you live in any of these states it is best not to touch the clock. That said, you know what to do come Sunday. Don't forget to share this information with your friends.

Why does the time change in Mexico?

From history, it is known that Benjamin Franklin wrote a letter in 1978 and had a savings proposal that sought to establish taxes so that they would have shutters and in these could not pass the light, also moderated the consumption of wax and candles, as well as prohibited the night traffic with church bells ringing in the mornings so that everyone would get up at an exact time to start their day.

In Mexico, the time change began to be implemented during the government of Ernesto Zedillo Ponce de León in 1996, to take advantage of natural light. Its main objective was to save electricity, and since then it was established that daylight saving time would be from the first Sunday in April to the last Sunday in October in most of the country.

Pros and cons of daylight saving time


Daylight Saving Time has many darker and shorter days compared to Daylight Saving Time. The act of setting the clock back one hour will cause people to conduct their activities with sunlight. So the days will have less daylight time and will seem shorter and the nights will seem longer, as the sun rises and sets earlier.

In the wintertime, the sun will start to rise at 6:30 am and will set around 7:00 pm. During wintertime, the body receives fewer hours of daylight. According to experts, this favors a greater secretion of melatonin, a hormone that helps us to fall asleep, that is, we rest more and better.


Our days will have fewer hours of natural light and may seem much shorter than before because night falls quickly. Having fewer daylight hours during the day could also increase robberies and road accidents. A report by the Observatorio Nacional Ciudadano (National Citizen Observatory) states that the evening is the time when most crimes are committed in Mexico City.

Studies by experts also point out that during daylight saving time, people tend to take advantage of sunlight and this is reflected in the consumption of electricity. This is why returning to wintertime could increase the consumption of electric energy since it gets dark earlier and we will have to resort to artificial lighting.

How to combat the time change?

Modify your bedtime routine 3 days before the time change. This can help alert your body and mind that you are changing something.

Take advantage of every moment of sunshine (and vitamin D). As explained, vitamin D is related to mood (among others), so take advantage of sunny times of the day as you can to come in contact with sunlight to promote its absorption.

Get regular physical activity and promote the release of endorphins. Try to establish a routine of physical activity to promote the release of endorphins, related to pleasure and well-being. If you were already physically active, keep it up despite the lack of sunlight.

Take care of your social life. Do not let the lack of sunlight prevent you from doing those social activities that you used to enjoy and that helped your mood: keep meeting friends, going out for a walk, etc.

Seek professional advice. These guidelines can help you to adapt a little easier, but if after one or two weeks you still perceive difficulties derived from the time change, you must go to a psychologist to assess your case and see how to overcome this situation in the best possible way.
